Abstract

A manually-powered, adaptive ladder lift system for hoisting objects along a ladder to a predetermined height is provided. The ladder lift system may include a stop assembly, a trolley assembly, and a headstock assembly adapted to engage the ladder, whereby the trolley assembly rolls along the side rails of the ladder between the headstock assembly mounted to the top of the ladder and the stop assembly mounted to a lower portion thereof. The headstock assembly is adapted to various types and sizes of ladders. The stop assembly is adapted to retain the trolley assembly at the predetermined height anywhere between the stop assembly and the headstock assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority of U.S. provisional application No. 61 / 982,128, filed 21 Apr. 2014, the contents of which are herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to ladder lifts and, more particularly, to a manually powered, adaptive ladder lift system for hoisting objects to a higher level.[0003]During construction jobs, a construction worker typically has to use the ladder supplied by the lift company. As a result, the construction worker needs to use the ladder hoist also provided when wanting to lift an object to a predetermined height. Typical ladder hoists have the following disadvantages: they must travel all the way to the top of their assemblage to stop the object-carrying trolley, they are motor-powered and so come the attendant motor issues, they are complicated to attach to the ladder and must always be attended when in use, they are heavy and hard to m...
